Title: Filament wound tube mfr. - in which coated filaments pass over concave surface which is tilted at each longitudinal winding change (NL 29.1.79)
Inventor: MAGARIAN GERALD MALCOLM
IPC: D04H1/64
Filed: 1978-07-25
Abstract: A filament wound tube is produced by impregnating a number of filaments with resin and winding them as a band to and fro along a rotating mandrel, passing them over a concave surface which lies at an angle to the filaments. This surface is tilted as the filaments return longitudinally so as to remain at a constant angle between the filaments and mandrel, the wound band is applied to the mandrel at a set helical pitch which arises from the longitudinal movement of the filaments and the mandrel rotation speed. System permits winding a wide band of filaments at uniform intervals with the only deviations from the winding angle occurring at the short winding ends.

Title: Daisy type print wheel - has print hammer adapted to impact selected element when wheel stopped
Inventor: RAGLAND III EVAN L
IPC: B41J1/24
Filed: 1978-10-06
Abstract: The daisy type print wheel is continuously driven through a magnetic clutch arrangement. Characters are selected by actuation of either an electromagnetic brake acting on the print wheel or a toothed character selector acting on the spokes of the print wheel. When a character is selected and the print wheel is stopped, rotation of the motor continues because of the slippage of the magnetic clutch. Other features include a fast recovery time for the hammer because of its constant rate of actuation, and change in spacing by varying this constant rate and also an improved carriage scan technique which provides for fast return.

Title: Cutting extrusion with automatic control - where circuits provide set acceleration and deceleration of cutter swinging through its arc
Inventor: SCHWARZ THEO
IPC: B26D1/62
Filed: 1979-10-15
Abstract: Plastic extrusions and similar materials are cut off to length using a shear cutter electrically driven and swinging about an axis parallel to the material which is moved by operating a switch after each cut. The cutter blade is fixed to the shaft of a DC motor which operates in steps, each step being one revolution; the speed of revolution is measured and signalled, pref. by a generator; the motor and speed indicator are connected to an electronic control set for given speeds, which compare the motor acceleration, after cutting, with a nominal value and which stops acceleration beyond that value. An induction switch is positioned at 150 deg. on the arc described by the cutter in front of the cutting point; as the cutter approaches this switch feeds a current to set the position of rest of the cutter; a second similar switch on the arc beyond the cutting point changes the polarity of supply to the motor as the cutter passes and hence produces a braking effect. Efficient operation is provided as machine is suitable for mass prodn. and therefore at low costs, minimal mechanical loads and wear on parts, minimal noise level in operation.
